# NAME

posix_spawnattr_getsigmask, posix_spawnattr_setsigmask — get and set the spawn-sigmask attribute of a spawn attributes object

# LIBRARY

Standard C Library (libc, -lc)

# SYNOPSIS

#include <spawn.h>

int
posix_spawnattr_getsigmask(const posix_spawnattr_t *restrict attr, sigset_t *restrict sigmask);

int
posix_spawnattr_setsigmask(posix_spawnattr_t *attr, const sigset_t *restrict sigmask);

# DESCRIPTION

The posix_spawnattr_getsigmask() function obtains the value of the spawn-sigmask attribute from the attributes object referenced by attr.

The posix_spawnattr_setsigmask() function sets the spawn-sigmask attribute in an initialized attributes object referenced by attr.

The spawn-sigmask attribute represents the signal mask in effect in the new process image of a spawn operation (if POSIX_SPAWN_SETSIGMASK is set in the spawn-flags attribute). The default value of this attribute is unspecified.

# RETURN VALUES

The posix_spawnattr_getsigmask() and posix_spawnattr_setsigmask() functions return zero.

# STANDARDS

The posix_spawnattr_getsigmask() and posix_spawnattr_setsigmask() functions conform to IEEE Std 1003.1-2001 (“POSIX.1”).

# HISTORY

The posix_spawnattr_getsigmask() and posix_spawnattr_setsigmask() functions first appeared in FreeBSD 8.0 and imported for NetBSD 6.0.
